Hey everyone, I just found this board thanks to Pinky, thought I'd join up. I'm pretty new to bikes, but I've done a ton of tuning on cars and I have a ton of experience in engine setups, turbo setups, dyno tuning, etc.
We started playing with e85 years ago and its awesome. 105 octane on paper, but you can get away with a lot more than you can with straight gasoline that is 105 octane. I make 650whp on my 11:1 2.0 liter honda motor on e85, it didnt even blink, wanted more :)
I just boosted my 2005 busa, 100% stock motor. RCC stage 1 but I built my own fuel system and I'm running an Autronic SM4 standalone. If you didn't see the charts elsewhere, here's the info. Back to back, same day, same boost (6.5psi at redline), only changes are the calibration and the fuel (91 to e85).
91 versus e85 back to back.
all-motor versus e85
plot of boost and a/f (reading gasoline a/f units, but its e85)
I want to mention that I'm on a dyno dynamics car dyno, which reads lower than "car" dynohets, but I'm also at high altitude (Colorado) so the corrcetion factor is overinflated. The thing to take from this is the changes. A dyno is just a tool, the MPH at the track shows the actual power. The dyno lets us track changes and do tuning, so look at what I gained over all-motor, and what I gained switching to alcohol.
E85 cools valves, combustion chambers, etc. bigtime - you can pretty much get away with murder with it LOL
Feel free to ask any questions if ou want to know anything, I'll try to help. Probably tuned well over 100 cars on this stuff by now.
